Extract value from GUI from playback file
CentraleJe

in OpenBCI_GUI
Hi Everyone,
I am new in the community. I don't receive my ganglion board for now, but I want to take a lead in my project!
I looked for a solution to extract the values of the concentration widget from a playback file to put it in a local server and send it to my arduino.
I download the OpenBCI_guide and the file OpenBCI_GUI-v5-blinks-jawClench-alpha.
I read the OpenBCI Docs, forum and Github and I found the LSL tool but as far I understand the comments on the forum and my attempt to use it. LSL tool is not appropriate to achieve my task.
Is there a solution to extract the concentration widget value? If there is also an easier method to send the data to the arduino without the local server, I am interesting to!
Kind regards,
Jeremy

Jeremy, hi.
Have you looked at the Networking Widget and its detailed guide document?
Scroll down the guide document until you reach the Focus section. In the righthand column, you can see what will be sent to your Arduino serial port. Note this is sending directly to a local usb serial port device, not involving LSL or "local [networked] servers".

Another alternative you have (after receiving the Ganglion) is to write your own small Python program that receives in real-time, the data stream from the Ganglion. You then call the Brainflow classification functions. And write to the serial port yourself.

Thank for your quick answers! @wjcroft
I will have a look because I didn't noticed this part on the OpenBCI guide! In fact, I was aware of how to perform it with the ganglion board but the program you recommend me will spare me a lot of time !!
Thank you very much !!
